UNLABELLED The Drug-Induced Liver Injury Network (DILIN) studies hepatotoxicity caused by conventional medications as well as herbals and dietary supplements (HDS). To characterize hepatotoxicity and its outcomes from HDS versus medications, patients with hepatotoxicity attributed to medications or HDS were enrolled prospectively between 2004 and 2013. The(More)
UNLABELLED Hepatitis C virus (HCV) infection typically results in chronic disease with HCV outpacing antiviral immune responses. Here we asked whether innate immune responses are induced in healthcare workers who are exposed to small amounts of HCV, but do not develop systemic infection and acute liver disease. Twelve healthcare workers with accidental(More)
BACKGROUND T-cell responses have been described in seronegative patients who test negative for hepatitis C virus (HCV) RNA despite frequent HCV exposure. However, the cross-sectional design of those studies did not clarify whether T cells were indeed induced by low-level HCV exposure without seroconversion or whether they resulted from regular acute(More)
Portal hypertension has been described in a wide variety of hematological disorders, especially myeloproliferative and lymphoproliferative disorders. Its clinical manifestations may include bleeding esophageal varices, ascites, or hepatic encephalopathy. In patients with hematological disorders, there are a number of potential causes of portal hypertension,(More)
Studies on hepatitis C virus (HCV) replication have been greatly advanced by the development of cell culture models for HCV known as replicon systems. The prototype replicon consists of a subgenomic HCV RNA in which the HCV structural region is replaced by the neomycin phosphotransferase II (NPTII) gene, and translation of the HCV proteins NS3 to NS5 is(More)
OBJECTIVES To examine the medical status of children with biliary atresia (BA) with their native livers after hepato- portoenterostomy (HPE) surgery. STUDY DESIGN The Childhood Liver Disease Research and Education Network database was utilized to examine subjects with BA living with their native livers 5 or more years after HPE and to describe the(More)
BACKGROUND Acute liver failure (ALF) is a rare syndrome of severe, rapid-onset hepatic dysfunction-without prior advanced liver disease-that is associated with high morbidity and mortality. Intensive care and liver transplantation provide support and rescue, respectively. OBJECTIVE To determine whether changes in causes, disease severity, treatment, or(More)
Heparin-induced hepatotoxicity is well described in the literature, but rarely recognized clinically. Two cases were recently encountered. In the first case, elevated aminotransferase levels occurred after four days of heparin therapy. In the second case, enzyme levels increased after only 8 h of heparin treatment. To the authors' knowledge, this short time(More)
